The calculated TOI is indicated in the marker information. The markers required for
calculation are displayed in the marker table.
4. If the signal changes significantly during or after the TOI measurement, use the
"Search Signals" function to start a new signal search automatically and restart the
calculation of the TOI.

Measurement Example – Measuring the R&S
FSV/A's Intrinsic Inter-
modulation
A programming example demonstrating a TOI measurement in a remote environment
is provided in
Chapter 14.5.11.2, "Programming Example: Measuring the TOI"
Test setup:
Signal generator settings (e.g. R&S SMW):
Device
Level
Frequency
Signal generator 1
-4 dBm
799.6 MHz
Signal generator 2
-4 dBm
800.4 MHz
Setting up the measurement
1. Preset the R&S
FSV/A.
2. Set the center frequency to
800 MHz
and the frequency span to
3 MHz
.
3. Set the reference level to
-10 dBm
and RF attenuation to
0 dB
.
4. Set the resolution bandwidth to
10 kHz
.
The noise is reduced, the trace is smoothed further and the intermodulation prod-
ucts can be seen clearly.
